Specific embodiment

It should be noted that in the case where not colliding, in the embodiment and embodiment in the utility model creation Feature can be combined with each other.

The specific embodiment created below to the utility model elaborates.

A kind of oil field shaft mouth combination wrench of high intensity, as shown in Fig. 1 to 7, including holding rod 1, the holding rod one end are equipped with one Shaped wrench head 2, the other end are equipped with opened wrench head 3；Corresponding holding rod is equipped with one end of "-" type driving end, and being set with being capable of edge The axially adjustable socket head 4 of holding rod, and be equipped on holding rod for limiting the mobile locking mother 5 of socket head；Institute The linkage section 7 that socket head 4 includes active section 6 and is threadedly coupled with holding rod is stated, active section is integrally formed with linkage section Structure；The active section holding rod axial direction length, greater than "-" type driving end holding rod axial direction length；It will set When barrel spanner is adjusted under working condition, active section leans out the outer rim of "-" type driving end, can easily utilize sleeve barrel spanner Hand screws bolt or nut.

Socket head is screwed, the active section of socket head is made to protrude from "-" type driving end, screws locking again later Mother is resisted socket head using locking mother, plays the role of locking, when avoiding being screwed bolt or nut using socket head Rotation or displacement are generated, locking mother can be realized the limit to socket head, and it is firm to consolidate.

Holding rod is equipped with elbow 8 different from one end of "-" type driving end, and the opened wrench head 3 is hinged on the elbow front end. Above-mentioned holding rod surface is equipped with non-slip texture, increases the frictional force with palm, convenient for force.

Female locking and socket head while the limit sleeve 9 of rotation, the limit sleeve packet can be limited by being set on above-mentioned holding rod 1 Include the first limit section 10 and the second limit section 11；First limit, 10 inner wall of section is equipped with and locks six in female outer-hexagonal cooperation Square structure, the second limit section 11 are equipped with and six sides/interior four in outer six side of socket head active section outer wall/outer four directions cooperation Square structure.

Without direct connection relationship between limit sleeve and locking mother and socket head, it is not necessary to which additional uses connection Part connection, only need to engage positioning, convenient and efficient, only need to be by limit sleeve to (i.e. different on the inside of holding rod when needing to release limit In socket head active section side) it is mobile.

The thread rotary orientation of above-mentioned locking mother 5 and 4 linkage section of socket head is on the contrary, socket head and locking are female not Meeting rotation in the same direction simultaneously, locking mother play the role of good abutment sleeve spanner.Bolt is being screwed using socket head When, due to socket head stress, its own has the tendency that rotating, then, the limit being sleeved on the outside of socket head Set can limit the rotation of socket head, due to locking the oppositely oriented of female rotation direction and socket head, sleeve barrel spanner It can not rotate simultaneously between locking mother at hand, that is to say, that limit sleeve can be good at limiting socket head rotation, Ensure the work that socket head can be stable.

Socket head and "-" type driving end are equivalent to knockdown Wrench, are highly convenient for operating, and integrated level is high, The two can be used selectively, and mutually without influence, use process is reliable and stable.

Above-mentioned elbow 8 includes stretch section 12 and the changeover portion 13 that connect with the holding rod, in stretch section towards open spanner One end at hand is equipped with the flat segments for connecting with opened wrench head；The angle of the stretch section and holding rod is 120-150 °, The flat segments are parallel with holding rod.Why stretch section and holding rod design it is at a certain angle, be exactly in order to using elbow come When connecting opened wrench head, so that both opened wrench head and holding rod not on the same axis, can be more convenient for exerting a force.

It should be pointed out that changeover portion 13 is arcuate structure, transition connection can be played the role of, meanwhile, it is capable to avoid Stress is concentrated, and ensure that force-bearing situation is good between holding rod and elbow, is not easily broken.In addition, stretch section and holding rod fixture design For above range, also for avoiding stress from concentrating, meanwhile, also for mutually staggering, oil is insinuated into convenient for opened wrench head In the structural member of field wellhead assembly, the realization torquing operations being more easier, because using opened wrench head, can not only revolve Common bolt or nut are twisted, corresponding nonstandard connector can also be blocked, easily screw, dismantle.

Above-mentioned opened wrench head 3 includes base portion 14, which is equipped with wrench opening 15, and the other side is equipped with limiting slot 16；In the flat segments insertion limiting slot of the elbow, and pass through hinged shaft 17 and base hinge.It is screwed using opened wrench head one end When operation, flat segments will receive the limit of limiting slot two sides cell wall, and the width of limiting slot is generally 0.1- bigger than the width of flat segments 1mm or so, flat segments, which are equivalent to, to be stuck in limiting slot, does not have excessive space of waving, when pushing holding rod rotation, is put down Straight section can be applied to opened wrench head active force, play the role of spanner.

And when utilizing the socket head or "-" type driving end of holding rod, opened wrench head can be rotated to 90 degree, That is base portion and holding rod is axially vertical, in this way, can easily rotate holding rod using opened wrench head as handle, be highly convenient for Force.

Above-mentioned holding rod is length-adjustable Telescopic shaft type structure, can according to need, adjusts the length of holding rod, to adapt to not Same use demand.The length of appropriate adjustment holding rod plays the role of extension bar, matches spanner space, reaches as laborsaving as possible Purpose, facilitate the disassembling section of oil-field well head device.

It is obvious to a person skilled in the art that the utility model creation is not limited to the thin of above-mentioned exemplary embodiment Section, and in the case where the spirit or essential attributes created without departing substantially from the utility model, it can be real in other specific forms Existing the utility model is created.

Therefore, in all respects, the present embodiments are to be considered as illustrative and not restrictive, this Utility model create range be indicated by the appended claims rather than the foregoing description, it is intended that by fall in claim etc. It is included in the utility model creation with all changes in the meaning and scope of important document.It should not will be any attached in claim Icon note is construed as limiting the claims involved.

In addition, it should be understood that although this specification is described in terms of embodiments, but not each embodiment is only wrapped Containing an independent technical solution, this description of the specification is merely for the sake of clarity, and those skilled in the art should It considers the specification as a whole, the technical solutions in the various embodiments may also be suitably combined, forms those skilled in the art The other embodiments being understood that.
